Analyst Chen Shu: Yesterday's strategy for Bitcoin and Ethereum yielded profits; pay attention to whether the upper resistance level is broken.

Analyst Chen Shu: Bitcoin and Ethereum strategies were profitable yesterday (January 28th). Pay attention to the breakout of the upper resistance level. Yesterday's article analyzed and suggested shorting Bitcoin at 9.02, resulting in a profit of 2500 points. Congratulations to those who followed the strategy – there was no hindsight bias! Looking at the daily chart, yesterday's daily candlestick was a red doji, indicating a short-term rebound to near the 30-day moving average (MA30) before being resisted and falling back. The overall trend is basically consistent with the article's analysis. Intraday, the short-term resistance level remains the 60-day moving average (MA60) around 90,000. On the 1-hour chart, yesterday's short-term attempt to break above the 256-day moving average (MA256) failed. Short-term support is below the previous low of 8.7. Intraday trading suggestion: first, short at 8.90/90,000, then short again at 8.7 to go long for a small rebound. From the daily chart, Ethereum's price rebounded to around 3060 (the 60-day moving average) yesterday before encountering resistance and falling back. The 3060/3100 level remains a key resistance level in the short term; a retest of this level could present a shorting opportunity for a pullback. On the 1-hour chart, the rebound tested the confluence of the 256-day moving average and resistance. Intraday, a shorting opportunity is suggested around 3000, targeting a pullback to 2900 before attempting a long position for a rebound. Midday Trading Strategy (Written at 13:20): BTC: Short at 8.85, add to short position on a rebound to 8.95, target 8.75/8.7; long position around 8.7/8.6 for a 1-2000 point gain. ETH: Short at 2985, add to short position on a rebound to 3020, target 2930/2880; long position around 2900/2850 for a 6-100 point rebound.
